The nucleus of the crystalline lens stiffens with age and the ciliary muscle, which takes care of sight accommodation, loses elasticity. The result is presbyopia or eyestrain which makes it difficult to focus correctly on nearby objects.
Refractive surgery uses a technique known as presbyopia surgery that improves the ability to see close up without the need for glasses or contact lenses. This surgery has the following advantages:
The procedure consists of the implantation of a multifocal lens that replaces the crystalline and is specifically designed to contributing to an exact rectification of distances, avoiding the use of glasses and reaching total correction of near, mid and far sightedness.
As well as eyestrain, myopia and hyperopia can be corrected by adapting the implanted lens by making it adjust to the specific corrective needs of the patient.
Presbyopia surgery can be combined with cataract surgery with the sole requirement of the lens being doubly adapted to resolve crystalline clarity and near vision accommodation.
